Induced current density in the human body using equivalent sources for low-frequency inhomogeneous fields

An efficient numerical source model is proposed to calculate the induced cu rrent densities in the human body from low-frequency inhomogeneous magnetic fields emitted by electronic devices. Due to the complex geometrical struc ture of electronic devices (e.g. household appliances, power tools), an eff icient equivalent source model based on magnetic elementary dipoles is used instead of the real device or the approximated source model (current loop) . Subsequently, the validity of the method proposed is confirmed.
